Deployment Errors on GooglePlay

Hoping I can get a some assistance here, I am trying to release my App on Google Play but this has resulted in the following error warnings (see attached).

I hoping somebody might be able to help me address these issues. I have added Privacy Policy details to address the Major Error but the warnings related to uploading a deobfuscation file and debug symbols I have no idea how address in AppSheet.

Any ideas would be greatly appreciated.

Please contact support@appsheet.com for help with this.
